Problems solved by technology

[0003] However, the above-mentioned expansion method consumes a lot of labor, and many links need to be completed manually, and the speed is very slow
At the same time, it is necessary to use an oven for heating and compressed gas expansion during expansion, which consumes a lot of energy
In addition, due to the defects of the above-mentioned process itself, it is also necessary to manually cut off the uneven ends of the short tube after expansion.
And because the irradiated materials cannot be recycled, a lot of materials are wasted

Embodiment Construction

[0030] The present invention will be described in detail below in conjunction with the implementations shown in the drawings, but it should be noted that these implementations are not limitations of the present invention, and those of ordinary skill in the art based on the functions, methods, or structural changes made by these implementations Equivalent transformations or substitutions all fall within the protection scope of the present invention.

[0031] Such as figure 1 As shown, the continuous expansion process of the heat-shrinkable insulating tube of the present invention sequentially includes: irradiation, preheating, continuous expansion, cleaning, and cutting.

[0032] S1. The heat-shrinkable insulating tube is irradiated.

[0033] This step is used to realize the irradiation in the continuous expansion process. In step S1, after the heat-shrinkable insulating tube is irradiated, it does not need to be cut according to the traditional process.

[0034] S2. Preheat...

Abstract

The invention provides a thermal-shrinkage insulation tube continuous expansion process and a device, wherein the thermal-shrinkage insulation tube continuous expansion process comprises the following steps of S1, performing irradiation treatment on a thermal-shrinkage insulation tube; S2, preheating the irradiated thermal-shrinkage insulation tube; S3, after completely preheating, continuously expanding the whole thermal-shrinkage insulation tube; after the expansion, cooling and moulding; S4, washing the surface of the thermal-shrinkage insulation tube which is processed in step S3; S5, automatically cutting the washed thermal-shrinkage insulation tube. By the thermal-shrinkage insulation tube continuous expansion process provided by the invention, the complicated processes of sectionalized expansion are reduced; the degree of automation is improved; an integrated automatic expansion procedure is formed; the working efficiency is improved; labour costs are greatly reduced.

Description

technical field [0001] The invention relates to an expansion process, in particular to a continuous expansion process and device for heat-shrinkable insulating tubes. Background technique [0002] One of the links in the production of heat-shrinkable insulating tubing is the need to expand it. At present, the existing expansion method is as follows: firstly, the irradiated heat-shrinkable insulating tubes are manually cut into fixed lengths, and then heated one by one in an oven. After the heat-shrinkable insulating tube is completely heated, the artificial expansion bag is placed in the copper tube using compressed gas to expand one by one, and finally cooled with water. [0003] However, the above-mentioned expansion method consumes a lot of labor, and many links need to be completed manually, and the speed is very slow. At the same time, it is necessary to use an oven for heating and compressed gas expansion during expansion, which consumes a lot of energy. In addition...
